To check if your Vegan Lilac Lemon Cake is ready:

Pro Tips for Perfect Results

Common Mistakes to Avoid

Using too many lilac flowers

Too many blossoms can make the cake slightly bitter. Stick to about ½ cup loosely packed petals.

Overmixing the batter

Overmixing can make the cake dense instead of fluffy.

Skipping the acid

The lemon juice and vinegar help activate the baking soda. Don’t skip them.

Recommended Tools

These tools make baking easier:

Mixing bowls
Silicone spatula
Microplane zester
8-inch cake pan
Cooling rack

A digital kitchen scale can also help measure flour more accurately.
